Manchester United striker Dimitar Berbatov's future remains up in the air after former club Bayer Leverkusen ruled themselves out of the running for the wantaway forward.

With the 31-year-old featuring in just 21 games in all competitions last term, Berbatov said earlier this month his time at Old Trafford is "running out" and that he no longer feels valued at the club he left Tottenham for in 2008.

Berbatov's agent Emil Danchev said recently his client, who took up an extra year's option on his contract in March, wants to play in the Champions League and that a potential move to French club PSG was attractive.

One club that will not be entering the race for Berbatov's signature, however, are Bayer Leverkusen, with whom the Bulgarian spent five seasons before switching to Spurs in 2006. Chief executive Wolfgang Holzhauer says that, while the player is one on their radar, the German side will not be able to meet United's asking price.

He told the Rheinische Post: "We are looking to find a striker, one that works well alongside Stefan Kiessling. However, the return of Berbatov is not an option for us. We are still on good terms with him but he would only be an option if he was available on a free transfer."
